Can I use yoghurt or kefir instead of capsules with probiotics?
Yes, but you have to make sure that the yoghurt or kefir is at most slightly sweetened (the bacteria need sugar to survive) and contains live acidophillus and bifido-bacteria, and that the yoghurt or kefir is very fresh. You can “potentiate” the yoghurt by mixing it into salad, thus spreading the bacteria out over a very large surface area. For best results, mix probiotic bacteria-powder into yoghurt or kefir. Even better is to culture your own yoghurt with optimal probiotic bacteria. You can read how to make your own yoghurt here.
